The mini design of using xcat inventory templates to setup xCAT cluster with ansible
As a xCAT user, I can setup xCAT testing/production cluster rapidly with ansible, I can testing things in a testing environment, then rapidly setup production cluster.
As a xCAT user, I have ansible node host1, xCAT automation playbook and xcat-inventory data in github. I want to use ansible to setup host2 as xCAT MN cluster rapidly. (host1 and host2 can be the same host) The steps:
- Make sure ssh password-less between host1 and host2.
- git checkout xCAT ansible playbook
xcat-automation
on host1, runansible-playbook
command using main playbook under xcat-automation diretory to setup and configure xCAT cluster on host2. After the command is finished, xCAT cluster is ready on host2.
-
download xCAT from xcat.org, and install xCAT on target MN ------(Done, need to formalize the structure)
-
configure xCAT MN using xcat-inventory templates ------(#task55)
- configure site object
- configure passwd object
- configure networks object
- configure route object
- configure policy object
- import node object
- import osimage object (pending)
-
switch Database (Mysql or Postgresql) ------(Not Done)
-
OS image management ------(partially Done, osimage template is not ready in xcat-inventory )
-
xCAT nodes management ------(Not Done)
- node.list
- node.delete
- node.update
-
xCAT network service management ------(Not Done)
- DNS
- DHCP
-
invoke OS provision ------(Not Done)
- rinstall/nodeset/rsetboot/rpower to invoke OS provision
The playbook is named xcat-automation
, its structure is at the end of this part. Here is the explanation of the structure.
-
xcat-automation
is the playbooks top directory name. It contains fast_cluster.yaml and 3 directories (templates
,cluster.example
andansible
). -
fast_cluster.yaml is basic cluster configuration file
-
templates
stores xcat-inventory templates file -
cluster.example
stores configuration example files for advanced scenarios, for example, configuration files for using mellanox_cuda osimage cluster. -
ansible
directory contains ansible playbooks.- the common directory contains non-xcat function playbook.
- the xcat directory contains xcat function playbook.
-
install.xcat
is to install xCAT using go-xcat. -
configure.xcat
is to configure xCAT MN using xcat-inventory templates -
nodes
is to manage node object -
osimage
is to manage osimage object -
database
is to switch db ( mysql, postgresql) -
provision
is to userinstall
ornodeset,rsetboot,rpower
to invoke OS provision
